Officials on the Hawaiian island of Kauai say they have rescued 121 hikers who became stranded by rising waters that made a stream impossible to pass.

The Kauai County Fire Department said Monday that 98 hikers flew out Monday after spending the night near the remote Hanakapiai beach on the Napali coast. Another 23 people were flown out on Sunday evening before dark.

They were on the Kalalau Trail, a popular day-hike and backpacking route along the rugged, undeveloped coast. The trail takes off from the road’s end near Ke’e beach.

The stranded hikers rescued Sunday included several children, including an 18-month old and a 12-year-old boy who was swept downstream but able to get onto nearby rocks.
